If the message ‘‘SERVICE dUE NOW’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty on page .Independent of the maintenance messages in the information display,
replace the brake fluid every 3 years.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 only if they are noisy.
NOTE: 1:

If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from diesel-
powered vehicles, replace every 15,000 miles (24,000 km).
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded results in higher
transmission and transfer temperatures. This requires
transmission and transfer fluid changes more frequently
than recommended by the Maintenance Minder.
If you regularly drive your vehicle under these conditions, have
the transmission and transfer fluid changed every 30,000 miles
(48,000 km).
If you drive regularly in very high temperatures (over 110°F,
43°C), in very low temperatures (under-20°F, -29°C), or towing a
trailer, replace every 60,000 mile (U.S.)/100,000 km (Canada)
Driving in mountainous terrain at very low vehicle speeds,
towing a trailer, or driving when fully loaded causes more
mechanical (shear) stress and fluid deterioration. This requires
differential fluid changes more frequently than recommended
by the Maintenance Minder. If you regularly drive your vehicle
under these conditions, have the differential fluid changed at
7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Have your dealer replace this filter
when this service is indicated by a
maintenance message on the
inf ormation display. It should be
replaced every 15,000 miles (24,000
km) if you drive primarily in urban
areas that have high concentrations
of soot in the air, or if the airf low

blades at least every six months.
Replace them if you f ind signs of
cracking in the rubber, areas that are
getting hard, or if they leave streaks
and unwiped areas when used.
To replace a wiper blade:
To raise the wiper arm, turn the
ignition switch to the ON (II)
position and activate the wipers
(see page ). When the wipers
are in the upright position, turn
the ignition switch off to stop the
wipers in that position. Raise the wiper arm of f the
windshield.

CONT INUED
Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly.
The tire pressure monitoring system
(TPMS) warns you when a tire
pressure is low. See page f or
more inf ormation. Even though your vehicle is
equipped with TPMS, we
recommend that you visually check
your tires every day. If you think a
tire might be low, check it
immediately with a tire gauge.
Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.
Check the air pressures when the
tires are cold. This means the
vehicle has been parked f or at least 3
hours, or driven less than 1 mile (1.6
km). Add or release air, if needed, to
match the recommended cold tire
pressures on page .If you check air pressures when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to0.4
kgf /cm ) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinf lated.
Youshouldgetyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.
While tubeless tires have some
ability to self -seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure.

Never use a puncture-repairing agent
in a f lat tire. If used, you will have to
replace the tire pressure sensor.
Havetheflattirerepairedbyyour
dealer as soon as possible.
For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb.
The following chart shows the
recommended cold tire pressures f or
most normal and high-speed driving
conditions.
For additional inf ormation about
your tires, see page .Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.
Youshouldlookfor:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherof theseconditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord.
Excessive tread wear. Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread lef t on
the tire.
A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.

If the indicator comes on repeatedly,
even though it may turn of f as you
continue driving, have your vehicle
checked by the dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.
If this indicator comes on
while driving, it means one
of the engine’s emissions control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance, it can
reduce your f uel economy and cause
increased emissions. Continued
operation may cause serious damage.
If you have recently ref ueled your
vehicle, the indicator could come on
because of a loose or missing f uel f ill
cap. You will also see a ‘‘TIGHTEN
FUEL CAP’’ message on the
inf ormation display. Tighten the cap
until it clicks at least once.
Tightening the cap will not turn the
indicator of f immediately; it can take
several days of normal driving. The indicator may also come on with
the ‘‘D’’ indicator.If the battery in your vehicle has
been disconnected or gone dead,
thesecodesmaybeerased.Itcan
take several days of driving under
various conditions to set the codes
again.
To check if they are set, turn the
ignition switch to the ON (II)
position, without starting the engine.
The malf unction indicator lamp will
come on f or 20 seconds. If it then
goes of f , the readiness codes are set.
If it blinks f ive times, the readiness
codes are not set. If possible, do not
take your vehicle for a state
emissions test until the readiness
codes are set. Ref er to
f or more inf ormation (see
page ). 315

However, if the brake pedal does not
f eel normal, you should take
immediate action. A problem in one
part of the system’s dual circuit
design will still give you braking at
two wheels. You will f eel the brake
pedal go down much f arther bef ore
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (seeon page ).
If you must drive the vehicle a short
distance in this condition, drive
slowly and caref ully.
The brake system
indicator normally
comes on when
you turn the ignition switch to the
ON (II) position, and as a reminder
to check the parking brake. It will
stay on if you do not f ully release the
parking brake.
If the brake system indicator comes
on while driving, the brake f luid level
is probably low. Press lightly on the
brake pedal to see if it f eels normal.
If it does, check the brake f luid level
thenexttimeyoustopataservice
station (see page ). If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.
If the f luid level is low, take your
vehicle to a dealer, and have the
brake system inspected f or leaks or
worn brake pads. 298

ÎThe burning of gasoline in your
vehicle’s engine produces several by-
products. Some of these are carbon
monoxide (CO), oxides of nitrogen
(NOx), and hydrocarbons (HC).
Gasoline evaporating f rom the tank
also produces hydrocarbons. Con-
trolling the production of NOx, CO,
and HC is important to the environ-
ment. Under certain conditions of
sunlight and climate, NOx and HC
react to f orm photochemical ‘‘smog.’’
Carbon monoxide does not contri-
bute to smog creation, but it is a
poisonous gas. The United States Clean Air Act
sets standards f or automobile
emissions. It also requires that
automobile manufacturers explain to
owners how their emissions controls
workandwhattodotomaintain
them. This section summarizes how
the emissions controls work.
In Canada, Honda vehicles comply
with the Canadian emission
requirements, as specif ied in an
agreement with Environment
Canada, at the time they are
manuf actured.
Your vehicle has a positive
crankcase ventilation system. This
keeps gasses that build up in the
engine’s crankcase f rom going into
the atmosphere. The positive
crankcase ventilation valve routes
them from the crankcase back to the intake manif old. They are then
drawn into the engine and burned.
As gasoline evaporates in the f uel
tank, an evaporative emissions
control canister f illed with charcoal
adsorbs the vapor. It is stored in this
canister while the engine is of f . Af ter
the engine is started and warmed up,
the vapor is drawn into the engine
and burned during driving.
The onboard ref ueling vapor
recovery (ORVR) system captures
the f uel vapors during ref ueling. The
vapors are adsorbed in a canister
f illed with activated carbon. While
driving, the f uel vapors are drawn
into the engine and burned of f .
